Introduction

In May 2012, a field evaluation was conducted to assess the impact of the Ventis Home Ventilation System on indoor air quality and overall home comfort in a Killarney Heights property. The test lasted for two weeks, during which the Ventis system was turned on for the first week and off for the second week. The house remained unoccupied throughout the test period, ensuring no artificial heating or cooling systems influenced the results.

Test Setup & Methodology

The home, a double-story brick construction with ceiling and wall insulation, was ideal for testing the Ventis system’s ability to maintain a comfortable internal environment in a typical Australian home. The system was evaluated under real-world conditions, without any intervention from external temperature controls. During the test:

  • Week 1: Ventis system running, actively circulating fresh air into the home.
  • Week 2: Ventis system turned off, allowing natural ventilation to take its course.

Results: Humidity and Temperature Comparison

Humidity Decrease Achieved with Ventis System On

One of the key outcomes of this evaluation was a noticeable decrease in internal humidity when the Ventis system was operational. By drawing fresh air from outside, the system helped reduce internal moisture levels, providing a more comfortable living environment.

Temperature Analysis

The graph below illustrates the impact of the Ventis system on internal temperatures compared to outdoor conditions over the two-week period:

  • Week 1 (Ventis system on): The internal temperature remained cooler, staying within 6 degrees of the external temperature, making the indoor environment more comfortable.
  • Week 2 (Ventis system off): Without the Ventis system, the internal temperature rose by up to 6 degrees, highlighting the significant cooling effect the system provides.

Conclusion: Improved Comfort and Air Quality

The two-week test demonstrated the effectiveness of the Ventis Home Ventilation System in improving air quality and temperature regulation in a home setting. When the system was operational, the house maintained a comfortable internal temperature and experienced lower humidity levels. When turned off, the internal temperature rose and humidity levels increased, emphasizing the importance of a continuous, fresh air exchange.

This case study confirms that the Ventis system is an effective solution for homeowners looking to enhance indoor air quality, maintain comfort, and optimize ventilation in both new and existing homes.

Very good service, fast and clean and pleasant staff. The Ventis system itself is a great idea and good money saver, esp. in colder periods of poor weather.

We have owned a Ventis ventilation system since 2015. The system is excellent and combines well with our new airconditioning/heating system to maintain a stable temperature in the house. Maintenance is roughly annual (change the main filter). We have ours serviced regularly. The service people have always been helpful, courteous, communicate their arrival beforehand, and efficient operators. We have worked out that it saves electricity because the aircon is not required unless the temperature inside is extreme (for us that is below 15ºC and above 28ºC). We highly recommend the system and the company. Our opinion is still current on 21 March 2025.
